Good evening,
I have used this website for years but this is my first time posting. I tried searching other topics but as I'm pretty good at learning, I'm not a computer expert therefore am lost on this issue. Thanks for the help.
I was on my computer when it locked up. I was on hotmail and a search engine at the time. When I rebooted it, It got stuck in a loop on the Advanced boot options menu. I had not downloaded any new hard/software anytime recently.
I tried safe mode, normal mode, and last known good configuration to no avail. It would just reboot to same screen. I pressed f8 and got to advanced options menu and disabled automatic restart on system failure. At that point it brought up the BSOD with this messsage.
UNMOUNTABLE_BOOT_VOLUME
***STOP: 0x000000ED (0x8A450c08, 0xC0000006, 0x00000000, 0x00000000)
My computer is a desktop HP Pavillion a1630n. I do not have any recovery discs, but seems to have Microsoft Windows Recovery Console option but when I chose it, just continues to loop to Boot options or to BSOD. I do not know what to do from here.
Any advice is greatly appreciated.

If you have available an XP, Vista or Windows 7 installation disk, any of them can be used to boot from and run chkdsk /r.

If you do not have the above ...

:step1: On a working computer, create a bootable XP Recovery Console CD.

Please download ARCDC from Artellos.com.
  • Double-click ARCDC.exe
  • Follow the dialog until you see 6 options. Please pick the appropriate selection, for example: Windows Professional SP2 & SP3
    • ( Replace "Windows Professional SP2 & SP3" with the OS required. <<< IMPORTANT)
  • You will be prompted with a Terms of Use by Microsoft: Please accept.
  • You will see a few DOS screens flash by: This is normal.
  • Next you will be able to choose to add extra files: Select the Default Files.
  • The last window will allow you to burn the disk using BurnCDCC.
  • Burn the .ISO image file to a CD, to make a bootable CD.

    (The ISO file is located on your Desktop.)
:step2: On the ailing computer, run chkdsk /r from the XP Recovery Console to repair the file system.
  • Insert the newly created XP Recovery Console CD in the computer's optical disk drive tray.
  • Start or re-start the computer so that it boots from the CD. You may be prompted to "Press any key". (If the system does not appear to be booting from the CD, you may need to enter the BIOS Setup Menu and change the boot order, so that the CD-ROM/optical disk drive is set to boot before the hard disk drive.)
  • When the Welcome to Setup screen appears, press the R key on your keyboard to start the Recovery Console.
  • The Recovery Console will ask which Windows installation you would like to log on to.
    If you have multiple Windows installations, it will list each one, and you would type the number (that is 1, 2, or 3 etc) associated with the installation you would like to work on (usually C:\Windows) and press the <ENTER> key.
    Please advise if you are not seeing C:\Windows listed.
    If you have just one Windows installation showing, type 1 and press <ENTER>.
  • You will be prompted for the Administrator's password. If there is no password, (and this is most likely), simply press <ENTER>.
  • You will be presented with a C:\Windows> prompt.
    Please advise if you are not seeing a C:\WINDOWS> prompt.
At the C:\Windows> prompt, type chkdsk /r and press <ENTER> (Note: There is a space between "chkdsk" and "/r")
  • This will take some time to run and at times may appear stalled but just let it run.
  • If any errors are found/repairs made, run chkdsk /r again, and repeat if necessary.
Type "exit" at the prompt and press <ENTER> to close the Recovery Console and restart your system.

Does Windows start normally now?

Ok, I made the XP recovery Console CD.



On the ailing computer, run chkdsk /r from the XP Recovery Console to repair the file system.
-when I click on it, it loops me back to either menu or the BSOD.

The Recovery Console will ask which Windows installation you would like to log on to.
Please advise if you are not seeing C:\Windows listed.
-I had 2 choices,
1: H:\MiniNT
2: H:\I386

What shall I do now? Thanks

Sorry, I can't imagine what this refers to, or what you might be doing.


-I had 2 choices,
1: H:\MiniNT
2: H:\I386

Those two choices represent the HP factory recovery partition (H:). What this means is the Windows file system is corrupted in a way that prevents the Recovery Console from actually recognising the C: partition as having Windows installed on it.

Log on to either of the two choices offered:
  • Type C: at the prompt and press <ENTER>
    You should now be looking at a C:>_ prompt.
  • At the C:>_ prompt, type chkdsk /r and press <ENTER>
    Chkdsk should now run.
  • When chkdsk completes, type exit at the prompt and press <ENTER> to restart the computer.

ran chkdsk /r. then computer rebooted.
Now message came up
The file isapnp.sys is corrupted. Press any key to continue.

Based on previous post, I am going to run chkdsk /r again. Is that correct. Keep running until no errors are found?

Oops, I was tired and forgot to take CD out.
Windows has come up normally.
THANK YOU! THANK YOU!

I'm disabled and on a fixed income so my computer is my life.
This site and people like you are such a blessing! Thanks again.

Good news!

Now, let's check and make sure all is well.

Use the Windows Error Checking utility (Check Disk), with the options to fix file system errors and scan the disk surface for errors, attempt recovery of data and repair the disk.
  • Open "My Computer"
  • Right-click on the drive that you wish to check > Properties > Tools > and in the "Error checking" section, click on "Check now".
  • Place a tick in both boxes > Start.
  • If the disk you have chosen is the system disk:
  • A message will notify you that a restart is necessary: Click OK, and close all windows.
  • Re-start the computer. The disk will be checked when the system boots.
    This test will take some time to run and at times may appear stalled but just let it run.
  • When the disk check is complete, the system will re-start automatically and load Windows.

A log of the disk check is recorded only if the scheduled re-start is used, and only for drives on the same HDD as the Operating System.
To open Event Viewer and view the log:
  • Go to Start > Run > and type eventvwr and press the <ENTER> key.
    The Event Viewer window will open.
  • In the left pane, click on Application.
  • In the right pane, at the top, click on the column heading Source to sort the list alphabetically.
  • Look in the Source column for "Winlogon", with an entry corresponding to the date and time of the disk check.
  • Double-click on that entry to view the log.
  • Click on the Posted Image button to copy the log text to the clipboard.
  • Paste the log text into your next reply.

12 KB in bad sectors.

That is not what we wanted to see unfortunately. The hard drive is failing. It will continue to fail over time .... as sure as night follows day ..... but it is not possible to predict the rate of failure or when it will next cause a problem for you.

I suggest that you replace the hard drive if and when you can to avoid future trouble. However, if you wish to continue to use this hard drive, you should remain prepared at all times for further strife.

Well, that stinks. *SIGH*
Thanks for getting it back up and running for me so I can at least download my documents and favorites right away before it dies for sure. I'll look into finding another computer soon. I really appreciate all your help.

That's life: That's the normal progression of things. Stress not about it!

Look at it this way: It's a good thing! You have been reminded to always keep a current backup of your documents and have the opportunity to do it before losing everything.

You can continue on your merry way as is: It might go for 3 or 12 months without a problem. It might not ever give you a problem again .... and one day you will be ready to get a new computer anyway.

All is good .... well, not so bad .... really.

I wish you the best of luck with it. Everybody loves a red-headed angel!
